Additional Informations

After checking log, it was found that the Language Server failed to include classes from workspace dependencies into the class path.

If the classifier of dependency is not specified, class path is constructed correctly.

Comienza con la solicitud workspace/executeCommand para vscode.java.test.runtime.classpath y reproduce el problema usando el ejemplo vinculado de varios proyectos con test001 en ServiceTestA. Compara el classpath devuelto cuando se especifica el clasificador de la dependencia y verifica que se incluya project-b/target/classes para que la prueba pase.
